湖南黑色岩系中的钒矿床

VANADIUM ORES IN BLACK ROCK SEQUENCE, HUNAN

湖南沉积型钒矿床主要分布于武陵山区、雪峰山区和湘中龙山地区等。钒矿床赋存于下寒武统底部黑色岩系层位中,以含钒伊利石形式存在,并伴有Ni、Mo、Cu、U多种元素。其成矿作用受雷峰运动后形成的坳陷盆地边缘陆棚沉积环境所控制,其富集与有机质和生物化学成矿有关。

Sedimentary-type vanadium deposits in Hunan are mainly distributed in Wulinshan, Leifengshan and Longshan area . Vanadium ores occured in black rock sequence in the bottom of lower Cambriam Series with the form of V-bearing illite,and associated with Ni.Mo.Cu.U . Its metallogenesis is controlled by continental shelf sedimentary environment in the margin of down-warp basin forming after the Xuefeng orogeny,and its enrichment is related to the organic material and biochemical mineralization .
